Selecting the Right Product Saves Time, Money, and Headaches
Chemical grouts are used before, during or after construction in a variety of applications including groundwater control, soil stabilization, void filling, encapsulation and structural lifting of concrete slabs. Because there are many kinds of chemical grouts it is important to review and match the needs of the project with the specific characteristics of the grout. For example, some resins are designed to permeate soil, rock or superfine cracks and cure with no expansion. Others are designed to fill large voids and expand up to twenty times their original volume. Some are shipped to the job site as a liquid which requires less mixing before injection, or in a granular form in order to maximize space on the jobsite and reduce shipping costs. Most of this caliber of information is available online, but consultation with the producer or a grouting consultant is recommended to insure the most appropriate product is selected. Occasionally grouting may be the primary goal of a project as it was in the Oak Ridge case study, but typically the use of chemical grouts are simply a means to an end; so that the project or construction can continue as planned. The injection of chemical grouts may be the only way to achieve the desired result (reduce permeability to a predetermined lugeon, or fill voids without adding extra weight to the soil, etc). Selecting the right product for the project will save the contractor from considerable head-aches and save the owner significant time and money.
